Florida Gov. Rick Scott said he'd been briefed on the incident and remained in touch with law enforcement.

"Over the past year, the Orlando community has been challenged like never before," Scott said in a statement. "I ask all Floridians to pray for the families impacted by this senseless act of violence."

The FBI's Joint Terrorism Task Force responded to the scene, according to photos.

Authorities closed off a section of Forsyth Road at Hanging Moss Road as the investigation continued.
